I think £705 for a 10x8 shed is pretty good value, but that isn't the point. If you aren't happy with the treatment & it doesn't match what was on display then hold out for proper compensation. Work out how long it would take to treat the shed and calculate the effective labour cost. Ask for that, plus a bit, in compensation.
As for the 9'7" as opposed to 10', I think you will probably find that somewhere in the small print they will say all sizes are approximate. Also, are you measuring the total length, including any roof overhang?
